I detest the term "fanboy" for a number of reasons, but mainly because it exists solely to poison the well in any discussion. It's like calling Republicans racists or Democrats communists, it immediately kills the possibility of meaningful discussion.
As for my use of Apple products...
As an artist, I appreciate good design, whether it's a printed page or valued tool. Apple has always been focused not only on the functionality of their products, but their aesthetic appeal as well. I agree with that emphasis, and I'm willing to pay for it.
But even more importantly, way back in the olden days of my industry when computers were making their appearance as "desktop publishing" tools, there was really only one viable solution for a designer interested in productivity and quality, and that solution was Apple Computers. So I boarded the Apple Train early on, and now I have a large investment in Apple hardware and compatible software, so I'm committed to the platform, even though Windows-based machines are at parity (and even better in some cases) when it comes to performance.
Having said that, I think it's obvious that Apple has changed their focus away from the professional market towards the large and vastly more lucrative consumer market, and their products are reflecting that focus. So while I still consider myself committed to the Apple platform professionally, I am not inclined to automatically upgrade to the latest Apple hardware or software. For example, I haven't upgraded to Lion (and won't until I am forced at gunpoint); I plan on running my 2008 Mac Pro until it turns to dust; and when it comes to upgrade my monitors, I will gladly ditch my Apple Cinema Displays for other models that have more calibration options.
As much as I like Apple products, it's vital for me to keep in mind they are just tools, and as such, are only valuable to the extent they help me get stuff done.
I guess this is just a rambling alternative to my signature line, but you asked.
